PHOENIX -- In the eighth inning, with his team trailing by two runs, D-backs manager Torey Lovullo looked at his lineup card and started thinking about which hitters might be good to match up against Rangers closer Jose Leclerc in the ninth.

Lovullo looked at the numbers that had been provided to him from the front office, and he talked with hitting coach Darnell Coles to solicit his opinion.

The consensus was that Jarrod Dyson was their best pinch-hitting option.

“We just needed to get someone on and have that situation line up,” Lovullo said.

Things fell just right as Dyson hit a pinch-hit walk-off homer off Leclerc to lead the D-backs to a come-from-behind, 5-4 win over the Rangers on Tuesday night at Chase Field.

“You try to identify the best targets when you’re going up against closers,” Lovullo said. “I had a lot of information in front of me. Darnell Coles and I had a conversation. We lined up the best possibilities through his eyes. You know, you trust your coaches, the ones that know them best, and then you make your decision."

Dyson didn’t look good when chasing a slider on the first pitch, and he fell behind 0-2, before evening the count at 2-2.

Then, Leclerc left a slider up that Dyson deposited over the right-field wall for his first career walk-off homer.

“That’s a tough guy to try and put a good at-bat against,” Dyson said. “I tried to just stick with my game plan and get a pitch I could handle. Obviously, I was chasing earlier in the at-bat, so I had to settle down and just see the ball and pick my pitch. I just tried to pick me a good pitch over the middle of the plate and tried to do a little damage with it. I ended up getting a pitch I could handle and got lucky.”

It was an exclamation point on Dyson's journey back from a core injury that cut his season short in 2017, and reoccurred in '18, causing him to appear in only 67 games last season, his first with Arizona.

“I’ve been busting my behind with the training staff,” Dyson said. “It’s just good to be back in uniform, put your spikes on, lace them up and be in the dugout with the guys. Just to be back out there is a great feeling.”

Before Dyson’s blast, the D-backs hit the ball around the yard against the usually reliable Leclerc. Christian Walker led off with a single, and he scored on Eduardo Escobar's double to center.

Nick Ahmed struck out, but Dyson, who was hitting for catcher John Ryan Murphy, then ended it.

“My fastball was there, and my changeup was there. Everything was good," Leclerc said. "They just hit whatever I threw.”
